We run a t-test that elicits a conclusion of p.05 B) p

Question

We run a t-test that elicits a conclusion of p<.01. Now, we draw samples that have twice the variation, but the rest of the statistics stay the same. Based on these new findings, which of the following cannot be true?
A) p>.05
B) p<.05
C) p<.01
D) p<.001

Quizplus · Accepted Answer

Increasing the variation in the samples generally increases the p-value, making it less likely to be smaller than the original p-value. Therefore, p<.001 cannot be true if the variation has doubled.
